OIL-INTERCEPTER.

SPECIFCATIONiformig part of Letterslatent No. 768,415, dated August 23, 1904.

Application led February 8, 1904.

To @ZZ whom t may concern:

Be it known that I, vTHOMAS RWVINeRovE, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements' in Oil-Intercepters, of which the followingis a speciiication.

This invention relates to an improved oilseparator or oil-intercepter for separating oil from any kind of gas, Aair, or vapor, such as ammonia or steam.

The invention consists of an improved baffle-plate structure, through which ispassed the gases, air, or vapors containing oil and by means of which the oil is intercepted or separated..

In ice-making machines there is a great'reduction of efiiciency` and much trouble and loss caused by oil carried by the ammonia gas through the machinery and piping and deposited in a'lm or coating on the inner surfaces. My improvement herein described' is particularly serviceable in this class of machines.

The invention is illustrated in the accomf panyingvdrawings and will first be described in connection therewith and then pointed out in the appended claims. p

Figure 1 is a vertical section of two cylinders. one of which-contains the improved bafiie-plate for separating oil from ammonia-gas.

. Fig. 2 is a horizontal cross-section, on alarger scale, of the cylinder and oil-intercepting baffle-plate. Fig. I3 is a perspvectiveview `o f the broad rear side of the upperY end of the bathe-plate.

In this improved oil-intercepter provision has been made for a relatively large surface or area of Ybafiie-plate, on" which the entire volume of ammoniagas'and oil-discharged from the compressor willl strike, the oil .being deposited thereon and then draining down- Ward and the gas passing through the` spaces or` openings in said baffle-plate.

Referring to the drawings, the letter A designates a case or cylinder having bottom and top heads I) c. This case has an 'inlet d,

which in the present instance is at the top head and at one side, and a pipe e for ammonia-gas and oil leads from the compressor (not semi No. 192,541. (Nb model.)

shown) and is connected with said inlet. Of course said inlet may be at any other part of the case. An outlet-pipev f leads from the case 'to carry off the depurated ammonia-gas. This outlet is at the other side. The improved oil-intercepter or baffle-plate has vertical cen' tral position in the case A and is between the inlet d and outletf. The baffle-plate forms a diaphragm or partition in the case. In the present instance two baiiie-plates are used.

The intercepter or bafflefplate is made up of y a number of sheet-metal strips e7 of certain shape placed vertically and parallel and overlapping each other and forming tortuous passages between. All the vertical strips are secured together by horizontal battens 71 to which each strip isfastened by rivets. Two battensv are used in the present instance. Each strip in cross-section has a shape approximating a letterV S, except instead of having a curved formation the parts are angular. Each striphas five surfaces. The surface 1 forms a concave back and rests against the batten,

zigzag or tortuous, is left between the adjoining strips It will be'seen that the ammoniagas, carrying mo're or-le'ss oil and entering one side of the case at the inlet d, will strike all the hoods of the relatively large bafiieplate and fthegases will enter the vertical l open spaces 6 to the concave back 1, the-n turn forward into theV hood and pass around the right-angled division 2, and then through the vertical open space 7 to the other side of the case. Where two of these baffle-plates are used, as shown in the drawings, the ammoniagas must pass through-the second one in the manner just described for the first. The effect of this constructionof oil-intercepter or baffle-plate is to provide a large surface for the adherence of oil and an unincumbered IOO downward drainage course or channel for the oil to the bottom of the case, and at the same time the gas will rise from the surface and pass through the vertical open spaces to the other side of the case and then upward and out through outlet-pipe f to a condenser. (Not shown.)

The oil-separator case has a gage fr' for showing the height of the oil.

A pipe r connects the two cylinders A J, and said pipe has a Valve la. This allows oil to pass from the separator-ease A, which in ice-machines is the high-pressure trap, to

vthe second ease, J, which is the low-pressure trap. A suction pipe Z leads to the compressor and is'for drawing o' the gas, and a pipem connects from said low-pressure case to said suction-pipe, and a valve m is in this pipe. A pipe n leads from the ease J to the condenser. (Not shown.) The oil left in the second ease after the gas has been drawn off is removed through pipe 0.

Vhile this oil separator or intercepter and ease has been here shown with a second ease, as it would be used in an ice-machine, it is to be understood that its one case may be used alone and with other machines than ieemachines.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. An oil-intercepting partition comprising a plurality of substantially S-shaped strips forming two longitudinal channels one opening from each side of said strips and the edge of one strip overlapping the oppositely-tu rned edge of the next adjoining' strip but separated therefrom to form a passage and means securing said strips together.

2. A device for separating oil from ammonia-gas, vapor or steam comprising a ease having at one side an inlet and at the otherside an outlet, and a partition in the ease between said inlet and outlet, said partition comprising a plurality of substantially S- shaped strips forming two longitudinal channels one opening from each side of said strips and the edge of one strip overlapping tlu` oppositely-turned edge of the next adjoining strip but separated therefrom to form a passage and means securing` said strips together.

3. In an oil-separatorcase, a partition made up of parallel vertical strips each one of which S. J oHN \V1LLIAMsoN, G. FERDINAND Voo'r
